-
Acidifiers: Organic acids (e.g., formic acid, propionic acid).
-
Antioxidants: Ethoxyquin, natural tocopherols.
-
Strong Oxidizing Agents: (e.g., potassium permanganate, hydrogen peroxide): Risk of sulfur oxidation, reducing bioavailability.
-
Alkaline Substances: (e.g., sodium hydroxide, excess limestone): May degrade methionine by altering pH.
-
Hygroscopic Additives: (e.g., choline chloride): Pre-mix with a dry carrier (e.g., wheat bran) to prevent moisture absorption and caking.
-
High Copper/Iron Levels: May chelate methionine, impairing absorption.
Product Details
FAQs
DL-Methionine is a synthetic essential amino acid used as a feed-grade supplement to optimize animal diets. This product contains ≥99% pure DL-Methionine in crystalline or powder form, providing a bioavailable source of sulfur-containing amino acids critical for protein synthesis, feather/fur development, and metabolic functions in livestock and poultry.
Methionine is the first limiting amino acid in poultry and swine diets. Supplementation improves growth rates, feed efficiency, and carcass quality, supports immune function, and reduces nitrogen excretion. It is especially vital for poultry to prevent feather pecking and promote healthy plumage.
Yes, it is safe and non-toxic when used as directed. Over-supplementation may cause amino acid imbalances or metabolic stress (e.g., reduced feed intake). Strictly adhere to recommended levels.
Yes, but adjust dosing based on bioavailability. DL-Methionine is directly utilized by animals, while hydroxy analogues (e.g., HMTBa) require metabolic conversion. Consult a nutritionist for equivalency calculations.
It should be stored in a dry, clean environment, protected from moisture, contaminants, direct sunlight, and extreme temperatures. When stored properly, it has a shelf life of 36 months in its original 25 kg/bag packaging.
Avoid mixing directly with strong oxidizing agents (which risk sulfur oxidation), alkaline substances (which may alter pH and degrade methionine), hygroscopic additives like choline chloride (without a dry carrier), and high copper or iron levels that may chelate methionine and impair absorption.
